The main shaft 3 carries a series of skew gears This invention relates to machines for making records on statistical cards, and has for its object to provide a machine which will automatically produce records representing data in serial or 5 progressive order, such as numbers.

A further object is to provide such mechanism of a simple form, and capable of operating at a high speed.

A still further object of the invention is to ,10 provide such a machine in which the feed of cards 15 forating machine will now be described by way of example with reference to the accompanying drawings.

Figs. 13 to- 16 inclusive are detail views showing the means to sense the presence of a card.

The machine comprises a base I on which is mounted a main frame 2 carrying a main shaft 3 driven through a pulley 4 and belt 5 from an 55 electric motor (not shown) housed in the base I.

6 from which pairs of feed rolls la., 1b, 'Ic are driven for transporting the cards through the machine.

'I'he cards are stacked in a magazine 8 from l which they are fed one by one by a picker 9 (Fig. 7) which is reciprocated by a pair of oscillating arms I0, Illa, pivoted on shaft I I.

The arm I0 is connected by a link Illb to an eccentric Inc secured to a shaft I Il) driven through skew gears IIOa from the main shaft 3.

Mounted to reciprocate vertically in the main frame 2.is a punch carrying frame indicated generally at I2. This frame I2 comprises a pair of side plates I3 connected by cross members I4 and carrying a guide plate I for the punches I6.

'I'he punches I6 are arranged in denominational columns and their heads I'I rest on the guide plate I5, their lower ends passing into a die plate I8, which is Xed in the main frame 2 and does not reciprocate With the frame I2. Be- A low this fixed .die plate I8 is a second die plate I9 having perforations into which the lower ends of the punches can enter. Between the die plates I8 and I9 is a narrow space 20 (Figs. 2 and 4) .2-

in which the card remains during the punching operation.

The card is fed into the space by the feed rolls 'la and is arrested thereon in the known manner by a card stop 20a carried between side plates I3. The card stop is carried by the reciprocating frame I2 and when the latter descends the card stop is in position to arrest the card. When the frame I2 ascends again the card stop is withdrawn and the feed rolls Ib eject the card which is carried to a receptacle (not shown) by the feed rolls 1c. Y

Mounted to slide along the top of the frame I2 is a series of punch setting slides 2|. Each slide 2I has secured to it a plate 22 from which depen-ds a setting finger 23.

The plates 22 pass between guide bars 24 running parallel to the side plates I3 and secured to the cross members I4. The slides 2| are further guided by a plate 25 under which they pass, this plate 25 running across the frame I2 between the side plates I3.

In addition the depending setting lingers 23 pass between guide bars 26 running parallelto the side plates I3 and secured at their ends to cross bars 21.

The frame I2 is guided in its reciprocation by vertical pillars 28 which are fixed in the main frame 2 and pass through holes in bosses 28a of the side plates I3.

The cross bars 21which unite the guide bars 2B are connected at their ends by bars 29 to form a floating frame which normally rests on niembers 30 which are secured to the cross members I4 of the frame I2 and in turn serve to carry the punch guide plate I5.

The bars 29 are guided on the upper reduced ends 3| of the pillars 28 and are held against the members 30 by springs 32.

The setting slides 2| move up and down with the frame I2 and the punches I6 and their action is as follows:-

If a setting slide 2| is disposed so that its nger 23 is over a given punch such as the punch Ia in Figure 2 then as the frame I2 descends thel slide 2| and its nger 23 descend with it and with the punches I6. As the frame I2 continues to descend the punches engage the surface of the card which at this time is disposed within the space 20. Those punches I6 over which no finger 23 is disposed come to rest on the card and are left behind as the frame continues to descend. The punch |6a, however, cannot move relatively to the frame since such relative movement is prevented by the finger 23 which is above the punch I 6a. The further descent of the frame I2, therefore, forces the punch Ilia through the card, thereby producing the required perforation therein.

Figure 4 shows the relative positions of the punches I6 which have not passed through the card, and of the punch Ia which has passed through the card. It will be seen that the finger 23 serves as an abutment for the punch Ilia, the thrust being taken by the plate 25 which prevents the slide 2| from tilting.

The punches which have been lifted relatively to the guide plate I5 are positively returned to their normal position by the guide bars 26 during the rise of the frame I2. In order to bring this operation about the pillars 28 are provided with shoulders 33 and during the descent of the frame I2 the floating frame formed by the bars 21 and 29 follows its descent until the bars 29 come to rest on the shoulders 33 just before the punches strike the card.

Thus the heads I1 of those punches which have been held up by the card will remain just below the guide bars 29 so that when the frame I2 begins to rise the pins I6 will be unable to rise with it until the members 30 have again engaged the bars 29 and commenced to lift the floating frame including the guide bars 26.

The frame I2 is reciprocated by eccentrics 34 secured to the shaft I Ill. In Figure l only one eccentric 34 can be seen, the other being at the opposite side of the machine. The strap 35 of each eccentric 34 has pivoted to it a link 36 pivoted at 31 to the frame 2 and at 33 to the lower end of a side plate I3 of the frame I2.

The machine according to the invention is intended to punch successive cards with holes representing numbers in serial order and means is provided for positioning the setting slides 2! automatically to effect this result.

In the machine shown in the drawings there are five setting slides 2 L, one for the units denomination, one for the tens denomination and so on up to the tens of thousands denomination.

In the drawings means is shown for setting al1 these slides automatically but it may be preferred only to set the units and tens slides in this way, leaving the remainder to be set by hand.

Setting racks 39 (Fig. l) which are slidablyv mounted in a Xed frame |39 abut against the cards.

ends of the slides 2|, being pulled against them by springs 4D.

The teeth of each rack 39 engage with a gear wheel 4i having fixed to it a co-aXial gear Wheel 42 engaging with a third gear wheel 43 having fixed to it a ratchet wheel 44. There is a ratchet wheel 44 for each denominational column of punches I3 which are required for punching serial numbers. The first of these ratchet wheels is the units wheel, the second is the tens, the third is the hundreds and so on.

Itis not normally required to punch serial numbers beyond five figures. It will be obvious that the sixth figure would only change after 100,000 Thus with a machine running at a speed of two hundred cards per minute, this change would only take place after every eight and a half hours running, and the operations would be more economically handled by rst separating the cards into batches.

All the ratchet wheels 44 are operated by a common stepped pawl 45 and, With the exception of the wheel of highest denomination all these ratchet Wheels have a deep tooth 46 in the nine position, so that when any Wheel reaches the nine position the next operation of the pawl 45 causes the neXt higher wheel to be advanced one tooth space, thereby eifecting a tens transfer operation as is well known in the art.

Since each ratchet wheel 44 is connected through the aforesaid gear wheels 4|, 42, 43 and rack 39, to its corresponding punch setting slide 2|, each advance of the ratchet wheel 44 will advance the corresponding setting slide 2| one step, which corresponds to the pitch of the punches I5. If when the setting slide 2| is in the 9 position, it has imparted to it a further movement, it is, according to the invention, automatically released from the ratchet wheel 44 and permitted to ily back to the zero position under the action of the spring 40. To this end the gear wheel 43 which is co-axial with the ratchet wheel 44, is formed without teeth over a part 41 of its circumference, this part being reached by the co-operating gear wheel 42 when the corresponding setting slide 2| is advanced beyond the 9 position.

Thus, during the advance of the ratchet wheel 44 from the 9 to the 0 position, the part 41 of the associated gear wheel 43 which is without teeth comes opposite the associated intermediate gear wheel 42 which is thereby freed from the action of the ratchet 44, and consequently the spring il pulls the setting slide 2| back to zero, this movement being arrested by a stop 39C (see Fig. 5) against which the corresponding rack 39 abuts when the associated setting slide 2| is in the Zero position.

The length 41 of the circumference of the gear wheel i3 which is formed without teeth is such that when it is in the Zero position, the intermediate gear wheel 42 which is connected to the rack 39 is free to move without its teeth touching the teeth of the mutilated wheel 43.

The rack 39, is therefore, released during the movement of the ratchet Wheel 44 from 9 to 0, and the next movement of the pawl 45 advances the setting slide 2| from the 0 to the l position.

The ratchet wheels 44 are operated during one quarter of the machine cycle and therefore the slide 2| has just over three quarters of the cycle in which to return.

From the foregoing it will be seen that as the pawl 45 operates the ratchets 44 step by step the setting slides 2| are advanced one unit at a time and when any slide reaches the 9 position the next movement returns it to 0. Thus, if the slides all commence their movement from the 0 position, then after, say, 123 operations of the pawl, the units slide 2| will have its finger 23 over the number 3 punch; the tens slide will be over the number 2 punch, and the hundreds slide over the number l punch.

It will be understood that it is necessary to advance the punch setting slides 2| one unit for each card fed to the punching mechanism as distinct from each cycle of the machine.

In order to ensure that this operation will occur, the actuation of the feed pawl 45 for the units counter described above is placed under the control of a sensing pin 50 (see Fig. '7) which ascertains at each'machine cycle whether a card is in the punching mechanism or not.

This sensing pin 50 is reciprocated under the die platesv I8, |9, between which the card passes and which are provided with holes for the passage of the pin 50. The pin is moved upwardly by a spring 5| and is drawn down positively by a cam 52 engaging a roller 53 carried on a member 54 from which the pin 50 projects, this member 54 being guided for vertical reciprocation in a part of the iixed frame 2.

Thus when there is a card between the die plates I8, I9, this pin 50 will fail to rise whereas when there is no card present the pin will rise to its fullest extent.

The lower end of the reciprocating member 54 which carries the pin 50 is pivoted to a lever 55 secured to a shaft 56 to which is also secured an arm 5l connected by a pin in slot connection 58 to a lever 59 pivoted between its ends on a shaft 60.

The other end 6| of the lever 59 carries a laterally projecting pin 62 on which rests an interposer 63 in the form of an arm freely pivoted at 64 to a lever 65 which when rocked actuates the units counter pawl 45 through mechanism hereinafter described.

Extending laterally from the interposer 63 is a projection 61 which, when the interposer 63 is in its lower position (Figure '7) is in the path of a lateral projection 66 on the arm ||l which actuates the picker 9.

When the interposer is in this lower position clockwise movement of the arm I0 brings the projection 66 into engagement with the projection 61 on the interposer 63 whereby the lever 65 is rocked in a clockwise direction about its pivot 65a and actuates the units counter pawl 45 by means of elements 69, 10, 12, 13 and '|5 (Fig. 1).

In Figure 7 the sensing pin 50 is shown as held in its lower position due to a card being between the die plates i8, I9, and accordingly the pin 62 on the lever 59 is also in its lower position whereby the interposer 63 is permitted to fall to its lower or operative position.

As already explained when there is no card between the die plates the pin 50 rises. Consequently the lever 59 is rocked in a counter clockwise direction and lifts the interposer 63 so that the lateral projection 66 is above the path of the projection 61. Accordingly the lever 65 and therefore the counter pawl 45 is not actuated when there is no card on the punching mechanism.

The lever 65 bears at its lower end against the head 68 of a rod 69 (Figures l and '7) pivoted at its other end to a bell crank plate 10, pivoted to the machine frame at 1|.

Also pivoted to this plate 10 is a rod '|2 guided for vertical reciprocation in the machine frame, the upper end of which lies under an arm 'I3 secured to a cross shaft 13a in the frame |39 of the punch setting units counter and pulled downwardly by a spring 14.

Secured to the shaft 13a is a further arm 15 connected by a pin in slot connection 16 to a lever pivoted at 'lla to theirame |39 and carrying the actuating pawl 45 which is pivoted to it at 45a.

This mechanism transmits to the pawl 45 the rocking movements of the lever 65.

The operation of the counting wheels 44 is arranged to take place while the setting slides 2| are rising immediately after the punches I6 are withdrawn from the card, and it is so arranged that the new setting is made by the time Vthe reciprocating frame l2 reaches the top of its stroke, thus ensuring that the setting is complete before the next punching stroke of the machine.

In operations requiring serial punching* of cards, it is sometimes necessary to punch such gures in conformity with a serial number which is. already printed on the card. In such cases it is very necessary to keep a very close check on the operations at all stages, and in one method used effectively the cards are dealt with in separate packs of 100 or 1000 cards.

During printing the cards can be separated into these batches. Then, as a next operation, each batch isV punched with the numbers common to the batch. It will be seen that in 100 batches all iigures above the rst two columns will be common to the batch, and in a 1000 batch, all above the first three gures will be common. On this operation these common figures would be set by hand for each batch, and the number checked by recording on a counter the number of cards. The serial number device would then only require to control the last two or three columns according to the size of the pack.

The most important feature of this scheme is that at the end of each batch the last card can be examined and checked with the recording counter to see that the printed number agrees with the perforated record.

The foregoing description assumes that the cards are kept in their separate packs which are dealt with independently. Now in order to effeet the same result without the necessity of separating the cards into packs, according to the invention a separate counting device is used which controls the number of cards which pass at any one setting.

With the aid of this counting device the whole pack of cards can be handled. The cards are put in the magazine of the machine with say No. 0 first. Assuming it is required to handle the cards in` batches of 100, the control counter can be set to 100, and the machine will then feed exactly 100 cards and stop on No. 99. The third :ligure is set by hand to l, the machine restarted, and Nos. 100 to 199 will be punched, the machine then stopping automatically for another setting.

As by this method the: cards are checked at every 100, errors of any kind are insured against and as the hand setting required for each 100 batch is only in respect of one gure, it makes a very economical and efficient method.

The counting unit which controls the stopping of the machine will now be described.

This control counter comprises a number of toothed wheels, conveniently two, of which one has 100 teeth, while the other 81 has only 10 teeth of a pitch equal to those on the other wheel. A common pawl 82 is provided to actuatethese wheels, and the wheel with the 100 teeth is pro vided with adeep tooth 83 at the 99 position so that the passage from 99 to O causes the pawl to advance the secondfwheel one step giving a reading of 100.

The actuating pawl 82 for the wheels of this control counter is carried by an arm 9| pivoted at 92 to an arm 90 rotatably mounted about the shaft 84 on which the counter wheels 80 and 9| are freely mounted, this shaft 84 being carried between supporting plates 85.

rlhe pawl 82 is actuated by the Same lever 65 which actuates the pawl 45 for the punch setting counter so that the control counter wheel 30 is advanced one step, only when a card is actually fed to the punches.

To this end the lever 55 is slotted at 86 and a bell crank plate 88, pivoted at 88a carries a pin 8l extending into the slot 85 andalso a further pin 89 extending into a slot in the upper end of the arm 99.

Thus each time the lever 65 is rocked the bel crank plate 88 is rocked also, which in turn rocks the arm 90 to operate the pawl 82 for the control counter.

The second wheel of the control counter which may be referred to as the hundreds wheel 8| carries a pin 99 which, when the hundreds wheel reaches the 0 position abuts against one arm 94 of a bell crank pivoted at so that when the other wheel 80 next reaches the 0 position the next stroke of the pawl 82 will advance the 100 wheel and cause a rocking movement of the bell crank 94. lThis rocking movement of the bell crank is transmitted to mechanism which interrupts the card feed.

The two wheels 80 and 8| of this counter are provided with means whereby they may be set to any desired number, for example, if it is desired that 275 cards shall pass through the mechanism before the card feed is stopped, then the first wheel 80, i. e. that with teeth is set to such a position that '75 steps of the operating pawl will bring this first wheel to the 0 position, while the 100 wheel 8| is set so that 2 steps of this wheel have to be effected before it reaches its 0 position.

With this setting the first '74 steps of the pawl 82 will bring the first wheel 80 to the 99 position. Then as it travels from the 99 to 0 position the l00s wheel 0| will turn one tooth.

Another 200 steps of the pawl 82, equal to two revolutions of the first wheel 89, will cause two further steps of the hundreds wheel 8|, the

last one bringing about a rocking of the bellcrank 90 to interrupt the card feed.

The wheel 80 is provided with a setting knob 95 and a graduated disc 96 bearing numbers from Zero to 99, while the wheel 8| carries a setting lever 9i projecting through a slot 93 at the side of which are graduations bearing numbers from 0 to 9, these representing hundreds.

Each wheel 80, 8|, is provided with a detent pawl l0|.

In order to interrupt the card feed the bell crank 94 referred to above is. provided with a shoulder |92 serving to hold down a slide |00 which tends to rise under the action of a spring |93, but is held down by the bell crank 94 of which the shoulder |02 engages a lug |05a on the slide, the bell crank 94 being pulled in a counter clockwise direction by a spring |04. This slide |00 is connected at to a stirrup member I|2 which lies underneath the cards in the magazine 8, but when the slide lilla` rises, the stirrup member ||2 also rises, thereby lifting the cards off the picker 9 so that the feeding is interrupted.

The slide |06 may also be connected by mechanism (not shown) to a switch controlling the supply of power to the motor which operates the machine so as to open the switch when said slide rises.

It will be seen that the means described above for lifting the cards off the picker 9 results in an instantaneous interruption of the card feed even if the picker makes a few more reciprocations after the motor has been switched off. It would clearly be of no value merely to stop the motor since it is desired to punch a definite number of cards and no more. For this reason the above means is provided for instantaneously interrupting the card feed by lifting the cards oi the picker 9.

After the slide has thus risen, it can be reset by depression of a key ||3 which in turn depresses the slide which is then latched again by the bell crank 94. The slide is also connected by a spring ||4 to the arm 9| carrying the operating pawl 82 for the control counting wheels 80 and 8| so as to lift this pawl off the wheels when the slide rises, thereby permitting the wheels to b-e reset if desired toy another number.

Where the rise of the slide |06 switches olf the motor, depression of the slide by the key H3 also serves to switch the motor on again.

When using this mechanism to control the punching of cards in batches of, say 100, as described above, the card counter can be set so that it will in effect reset itself after each 100 cards.

For this purpose the hundreds Wheel 8| would be set to its limit so that its pin 93 is resting on the arm of the bell crank 94. The first wheel 80 is then set at its first tooth so that after 99 cards have passed the passage of the 100th card will bring the rst wheel round so that the pawl 82 drops into the deep tooth, thereby sitepping the hundreds wheel forward by one s ep.

On release of the bell crank 94 (Fig. 8) the spring |04 attached thereto will return it to normal position, thereby moving the 100s wheel back one space to the position to which it was originally set. Further, the pawl will now again be in the first tooth of the first wheel so that the latter is also reset.

If the hundreds wheel is set at its first tooth and the first or units wheel is also set at its first tooth, the mechanism will be reset on release of the bell crank 94 after the passage of 1,000 cards.

If desired, two counters may also be operated from the member 12 which operates the counter for setting the punch slides 2|. These two counters, of which one is shown at I5, are of the visual type and from them can be read off the number of cards which have been punched. Both these counters are actuated simultaneously once for each card, but one counter may be reset to Zero after the passage of a group of cards so that it gives the total for each group, while the other counter is only reset after the passage of a number of groups and gives the grand total of all the groups.

In the construction described above the setting slides 2| are separate from the setting racks 39 and move up and down together withthe punches I6.

. Mechanism-according to the invention for setl, ting punches of this type is illustrated in FiguresV 9 to 12 of the drawings.

f In the. construction illustrated,- in these gures the lsetting slides are formed integral with the settingracks as shown-at |2|,in Fig. 9. The

slides |2| do not move up and down butaare provided with rack teeth |22 to engage with the gear wheels 4|. 1

The setting ngers in this case are in the form of pins |23 secured in sockets |24 at the endsof the slides |2|.

The punches |.6f restA freely by, their heads l10n a stationary plate |35 provided with perforation through which the punches pass. f

Mounted between the tops of the punches I6 and the lower ends of the pins |23 is a stationary connection box including connection rods .|25 which serve as interponents between the punches I6 and the setting fingers or pins |23. These interponent rods |26 are freely mounted in holes on plates |21, |28 forming part of the stationary connection box frame.

The plate |21 is provided with upstanding ribs |23a serving as guides for the setting lingers |23. Mounted above the setting ngers |23 and fixed on the frame of the machine is an abutment plate |29 against the underside of which the. upper ends of the setting ngers |23 abut.

,With this arrangement when a card is located between the reciprocating die plates and the lat-vv ter rise, the punches I6 will be lifted by the card.

Any punch over which a setting finger |23 isy disposed will be unable to rise, however, and consequently will perforate the card.

With this construction in which a card is moved and mounted in brackets |32 on the upper. dieu plates is a pair of bell cranks |33 pivoted at |34 each carrying a feed roll |35, |35a. The upward arms of the bell cranks are connected by a spring |36 tending to cause the upper feed rolls |35, |35a..to approach the lower feed rolls |3|, slots |41 being provided in the die plates through which the feed rolls can pass. v

The upward arm-of one of the bell cranks |33 is extended at |31 and carries a pin |30 which can engage with a hook |39 on a link |40 which is connected to a latch |4| adapted to engage with a finger |42 secured to the shaft 13a which operates the pawl 45 to actuate the control counter for the punch setting slides. The latch |4| is pulled in a clockwise direction about its pivot |43 by a spring |44 and the link |40 is pulled in a clockwise direction by a spring |45 against a stop |46.

Fig. 13 shows the position of the parts when a card is between the die plates |30 and the die plates are in their raised position. Under these conditions the feed rolls |35, |35a are resting on If desired the invention may be applied to av thecardand the pin 38 is in engagement with the hook |39, while the latch |4| is in engagement with the finger |42.l When the pin plates descend the feed roll |35a resting on the card maintains the arm |31 in the same vertical plane and, therefore, the pin |38 pulls the link |40 downwardly, thereby lifting the latch 4| clear of thel arm |42 as shown in Fig. 14. The spring 14 is, therefore, free to operate the pawl 45 when the member 12 is lowered.

Afterthe card has been punched the die plates |30'rise again and the pin |38, acting on theinclined surface of the hook |39, swings the link |40 in am counter clockwise direction whereupon the parts again `assume the position of Fig. 13.

'YI-he card is then ejected and if no further card is fed in,V then, when-the die plates rise from the position-v of Fig. 14 the spring |36 rocks the arm |31-in a counter-clockwise direction about its pivot. |34 as the die plates rise, this rocking being permitted by the slots |41 which are out in the dieY plates to receive the feed roll I35a. This swingingmovement of the arm|31 brings the pin clear of ther-hook |39 so that the parts assume the position shown in Fig. 15, the latch |4| being re-engagedwith the finger |42 by the action of the spring |44.

When the die plates |30 descend again the pin |38 passes under the hook- |39 leaving it unaffected so that the latch |4| remains in engagement with the finger |42 holding the shaft 13a against rotation so that the spring 14 cannot actuatethe pawl 45. The position of the parts when the die plates |30 are in their lower position and there is no card between them is shown in Fig. 16.

In Figs. 13 to 16 the link |40 has beenfshown directly pivoted to the latch member |4|. The connection between the link |40 and the latch |4| may', however, comprise any suitable linkwork, the nature of which will depend upon the relative positions of the die plates |30 and the shaft 13a in the machine.

An alternative mechanism for operating the counter which sets the punches is illustrated in from the main shaft 3 carries a cam 20| serving to actuate a lever 202 pivoted between its ends at 203 and pulled into contact with the cam by a spring 204.A The other end of the lever 202 engages an arm 205 secured to a shaft 206 carrying an arm 201 which is connected by a pin in -slot connection 208 to a lever 209 on a shaft 2 0 which carries the actuating lever 2|| for the pawl 45 which operates the ratchets 44 of the punch setting counting device.
